A new study published in the journal Nature Human Behavior on April 14, 2025, reveals that digital technology use is linked to a reduced risk of cognitive decline in older adults, challenging the common belief that it may harm cognitive health.

This comprehensive research, a meta-analysis of nearly 60 studies involving 410,000 participants, highlights the mental stimulation provided by engaging with evolving technologies, which acts as brain exercise that enhances problem-solving skills and adaptability.

The study emphasizes that the benefits of digital devices depend on their usage; while passive consumption may be detrimental, active engagement with technology can be beneficial for cognitive health.

Co-lead author Dr. Jared Benge noted that the positive effects of technology use on cognitive health persisted even after adjusting for factors like education and income, suggesting a genuine link.

The protective effect of technology use on cognitive health is comparable to other known factors, such as physical activity, which reduces risk by 35%, and healthy blood pressure management, which reduces risk by 13%.

While the findings are promising, researchers emphasize the need for further studies to confirm these results across diverse populations, particularly in low and middle-income countries.

Despite the overall positive findings, the relationship between social media use and cognitive health was inconsistent, indicating the necessity for additional research.

Concerns remain regarding the digital divide, as limited access to technology can exacerbate cognitive decline and social isolation among older adults.

Practical applications of digital technology for cognitive health include mindfulness and meditation apps, which have been shown to improve cognitive function and reduce stress when used regularly.

Participants in the study, referred to as 'digital pioneers', are older adults who began using technology later in life, often lacking internet access during their childhood.

Among the 136 studies reviewed, none reported an increased risk of cognitive impairment associated with technology use, a consistency described as 'quite rare' by Dr. Michael Scullin, another co-lead author.

As technology becomes integral to daily living, the focus should shift to enhancing its use to promote cognitive health, including maintaining social connections and fostering independence.
